The purpose of this thesis was to understand how energy is dissipated in various systems, in order to find general rules that can help increasing the energy efficiency of such systems.We mainly focused on membranes for ...

This thesis is a continuation of another thesis written by Botne (2017)1. SAPO-34 with different porosity was ion-exchanged with copper and co-exchanged with copper and silver. The materials were tested for selective ...

The aim of the thesis is to produce high grade silicon from off-grade materials like sculls and process slags from Elkem Thamshavn. The methods investigated are dense medium separation, optical separation, flotation and ...

Organic ligands play key roles in controlling the bioavailability of trace metals in the world oceans, thus influencing major biogeochemical cycles. The chemistry of organic ligands and the iron complexes formed, that in ...

In multi-level coupled cluster theory local orbitals have traditionally been generated us- ing Cholesky decomposition of the Hartree-Fock density matrix. Orbitals obtained through Cholesky decomposition are not very local ...

The cycling of iron in the ocean plays an important role within both the biological carbon pump and the nitrogen cycle. As much of primary production in the euphotic zone depends upon the internal recycling of iron, the ...

This is a benchmark study, for valence excitation energies in the multilevel coupled cluster
(MLCC) framework. The information resulting from lower level of theory is used to generate
correlated natural transition orbitals ...
